Why are imports deducted while calculating domestic product through the expenditure method?

Imports are deducted when calculating domestic product through the expenditure method because they represent spending on goods and services produced outside the domestic economy. The goal of the expenditure method is to measure the total value of goods and services produced within a country, known as Gross Domestic Product (GDP). Including imports would inflate the GDP figure, as it would reflect foreign production rather than domestic production. Thus, deducting imports ensures that only domestic production contributes to the GDP calculation.
